DISTI LLATE-BURNER.

Patented Sept. 14, 1915.

Application filed November 9, 1914. Serial No. 871,212.

To all whom it may concern Be it known that I, THOMAS E. Form, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles, State ofCalifornia, have invented a new and useful Distillate-Burner, of which the following is a specification.

The invention relates to distillate burners, such as are employed in ranges, furnaces, or the like, these burners employing a relatively low grade of petroleum fuel, such as commonly called fuel oil or distillate, which is difiioult to ignite and gasify but which when once gasified burns with an intense flame and high efliciency.

It is desirable in such burners to provide means for preheating or vaporizing the fuel before it is passed to the flame, and the principal object of the invention is to provide means for so vaporizing the fuel.

As such burners are used by unskilled labor and as they are subjected to great ex-- tremes of temperature, resulting in frequent injury to certain parts thereof, it is highly desirable that they be made in a form that will be cheap to construct and that they may be installed so that damaged parts may be readily removed and replaced when desired, and a further object of the invention is to provide a burner which will be of relatively few; p,arts,these parts being low in first cost and easily replaced. j 1n distillate burners used in ranges avery hot lire is required at times and a relatively slow fire is required atother times.

A further object of the invention is to provide a burner which may be utilized to produce an intense flame at times and in which the flame may be reduced when desired so portion of the range' with the invention. in

stalled therein. Fig. 8 is a partial section on the plane X -i 3 of Fig. 1. Fig. 4 is a cross section showing an alternative method of installing my invention. Fig. 5 illustrates a damper which may be used in either form of my invention but which is shown in place in Fig. 4.

Vhile I have illustrated my invention as applied to a range I do not restrict myself to such an application, as a similar burner may be used in any place where liquid fuel can be used.

The invention as illustrated consists of a prnnary pan 10 and asecondary pan 11. The primary pan 10 is cast in a single piece having a front lip 12 and a rear lip 13 and having side walls 14 and 15. A distillate supply pipe 16 is tapped into the front lip 12 and is supplied with distillate or other liquid fuel through a valve 17 from a pipe 18. The side walls 14; and 15 have ledges 19 formed thereon as-illustrated in Fig. 3 and the secondary pan is formed of a heating plate 20 having a front lip 21 and a rear lip 22 formed thereon, the heating plate 20 joining side walls 23 which extend downwardly and slide on the ledges 19 in the side walls 1-1 and 15 of the primary pan 10. A front deflector 21 rests on the side walls 23 extending completely across the front of the burner and being provided with a draft lip 25 which extends downwardly over the heating plate 20. A cup 26 is formed on the deflector 24 and a small opening 27 extends from the bottom of the cup 26 into the lip 25 approximately as shown in Fig. 1. A distillate supply pipe 28 extends over the cup 26 and is provided with a pet cook 29 by which the flow of distillate may be regulated, the distillate being dropped from this pet cock into the cup 26.

The above described parts are common both to the form shown in Fig. 1 and the form shown in Fig. 4. In the form shown in Fig. 1 a rear deflector 30 is formed integral'with the rear ends of the walls 23 and a loose deflector 31 is placed on top of the walls 23 extending completely across said walls and forming a tight joint with the deflector.

. The method of operation of my invention shown in Fig. 1 is as follows: The pet cook 29 being partially open, distillate, or other liquid fuel, is allowed to flow into the cup 26 and through the opening 27 into the secondary pan 11, overflowing into the primary pan 10 over the lip 22 which is slightly lower the primary pan 10 through the pipes 16 and 18 and valve 1?. "l e distillate is ignited in the lower pan, burning freely therein and heating the secondary pan 11, the flames passing upwardly between the lip 22, the deflector 30, and the loose deflector 31, and from thence upwardly into the upper part of the range 32 and outwardly through the passage 33 into the flue. The fire in the primary pan heats the heating plate 20 so that the fuel which drips into the. cup 26 from the pet cock 29 is vaporized as it'falls from the opening 27 onto the hot plate 20. This heating and vaporization of the fuel results in a veryintense hot flame and a very com-.

plete combustion. The amount of such I heating may be regulated by the valve 17 and after the the has been fully established the burning of fuel in the primary pan 10 may often be dispensed with. The combustion consists essentially of a double flame,

due to the fact that the air for combustion passes over both the lips 21 and the lip 22- meeting just above the central part of the pan l1 and uniting with the gasified fuel to form an intense flame. It will be noted that the secondary pan 11 together with the front deflector 24 and the loose deflector 31 are not rigidly connected to any portion of the stove, being simply inserted and resting upon the pan 10. They may therefore be drawn out of the stove without detaching any fastenings and new parts may be inserted in case the intense heat has injured any portion of the heater. The primary pan 10 being remote from the intense fire is not likely to be damaged and may be permanently installed in the range. I have found in practice that the loose deflector 31 being exposed to the fire from all sides is very likely to become injured from the fire and I have therefore made it in a separate piece from the secondary pan 11 and theside walls 23. For

convenience in castingthe front deflector 24 is also so formed, simply resting upon the top of the side walls 23. Where the range is of suitable construction the embodiment of my invention illustrated in Fig. 4 will prove very eflicient. In this form of my invention the deflector 30 and the hood 31 are omitted, the-side walls 23 being formed with rectangular ends and fitting against abody of fire brick 50 and under a projecting ledge of any application for which the invention is suited, it is highly desirable at times tohave a relatively less intense fire. For thepurpose of regulating the fireithe damper llustrated in Fig. 5 is used,this damper consisting of a rectangular member 52 having a handle. 53 formed thereon. The rectangular mem ber 52 is of such a size that it fits into the forward opening between the primary pain 10 and the secondaryrpan' ll, thus shutting off the draft which normally passes backwardlybetween the two pans and around over the lip 22. Projections 54 are provided on the member 52 so that it will be held in the opening.

While the invention has been illustrated as applied to ahotel range it is evident that it could be applied to furnaces used for other purposes, the particular embodiment shown beingchosen for illustrative purposes only. Further, although the burner has been shown with the forward end projecting through the wall of a range it is evident that in the case of other furnaces it may be desired to place it entirely'within the furnace, and I wish it distinctly understood that such.

an application falls within-the scope of my? invention. 7 V
